The Consumer Product Safety Commission (CPSC) issued a second warning this week following a house fire on October 23, 2017 in Manchester Township, Pennsylvania that destroyed one townhome and damaged four others.

More than 500,000 hoverboards have been recalled since a year ago. That changes with the CPSC's latest announcement.

So far there have been four reports fires but no injuries have been reported. CPSC first put out an alert in May, after another LayZ Board hoverboard started a fire that killed two young girls. The CPSC first issued a warning about the brand this past May, that warning itself following a house fire on March 10 in Pennsylvania.

According to CPSC, the products were manufactured in Shenzhen, China and more than 3,000 units were imported to the United States. All of these recalls are due to a risk of the products smoking, catching fire, and/or exploding.

Anyone who has one of these boards is encouraged to take the hoverboard to a recycling center where the li-ion battery can be properly removed and disposed of.

The recall also includes Sonic Smart Wheels scooters sold only in Louisiana, Drone Nerds hoverboards sold only in Florida.
